Well, bridges will probably have to be built, like for Rano to Connous; but I'm sure that's no problem at all.
By the sounds of it, you can get there from either of the places?
I'm supposing Courcle is in the center of Iria (where the map is covered in cloud) near Solea?
If so, each place probably has a connecting path.
I'll just fly an Eagle through Rano after taking a Mana Tunnel, and wait for someone to build a bridge (probably can't fly where there is no actual land, so no flying over without a bridge most likely).
We'll just have to wait and see.
